New YOLO models live in ultralytics/ultralytics

YOLOv5 remains available here for legacy projects, reproducibility, and users who specifically need the YOLOv5 codebase.

For all new Ultralytics models, current documentation, active development, and production workflows, use the main repository:

https://github.com/ultralytics/ultralytics

Use the main repo for new projects

The ultralytics/ultralytics repository is the canonical home for the current Ultralytics YOLO family, including:

• YOLO26, the latest stable recommended model generation
• YOLO11 and YOLOv8 support
• Detection, segmentation, semantic segmentation, classification, pose, OBB, and tracking
• Current training, validation, prediction, export, and deployment workflows
• Latest docs, examples, bug fixes, and releases

Install the current package

pip install -U ultralytics

Run YOLO26 from the current package

# Predict
yolo predict model=yolo26n.pt source=https://ultralytics.com/images/bus.jpg imgsz=640

# Train
yolo train data=coco8.yaml model=yolo26n.pt epochs=10 imgsz=640

# Track
yolo track model=yolo26n.pt source=https://youtu.be/LNwODJXcvt4

# Export
yolo export model=yolo26n.pt format=onnx imgsz=640

Python example

from ultralytics import YOLO

model = YOLO("yolo26n.pt")
results = model("https://ultralytics.com/images/bus.jpg")

When should I still use this YOLOv5 repo?

Use this repository when you intentionally need YOLOv5 scripts, YOLOv5-era behavior, or old project compatibility.
